<p>If an alias is not preceded and followed by a blank space, you must put the alias inside the <a href="#Bookmark1935"><b>${} Alias Interpreter</b></a> token.</p>
<p>The following example shows how to list all symbols, in all modules, whose function names match the pattern *CreateFile*. The alias @#ModuleName is not preceded by a blank space. Therefore,  it is put inside the <a href="#Bookmark1935"><b>${} Alias Interpreter</b></a> token.</p>
<div class="alert"><b>Note</b>  Do not confuse the @#ModuleName alias with the @#ModName alias. The @#ModuleName alias belongs to the <a href="#Bookmark2247"><b>!for_each_module</b></a> extension, and the @#ModName alias belongs to the <b>!for_each_function</b> extension.</div>

<p>You can put a sequence of commands in a command file, and use  <a href="#Bookmark1953"><b>$$&gt;&lt; (Run Script File)</b></a> to execute those commands for each function that matches the pattern. Suppose that a file named Commands.txt contains the following commands:</p>
<div class="code"><span codelanguage="cmd"><table>

<th>cmd</th>
</tr>
<tr>
<td>
<pre>.echo
.echo @#FunctionName
u @#SymbolAddress L1
</pre>
</td>

<p>In the following example, the commands in the Commands.text file are executed for each function, in the PCI module, that matches the pattern *read*.</p>
<div class="code"><span codelanguage="cmd"><table>
